Claims2
A process for the preparation of vinylglycol esters by reacting butadiene with oxygen and a carboxylic acid selected from the group consisting of formic acid, acetic acid and propionic acid in the liquid phase over a palladium-containing supported catalyst, wherein the catalyst used contains from 0.1 to 20 percent by weight of palladium and from 2.5 to 7 percent by weight of cobalt and has been heated at 400.degree.-900.degree. C. for from 15 minutes to 4 hours.
